Oxygen pressure high-pressure fan

Abstract

The invention discloses an oxygen pressure high-pressure fan. The fan comprises an oxygen pressure high-pressure fan body, a base is arranged on the oxygen pressure high-pressure fan body, a second-stage high-pressure bin base is arranged in the the center of the upper portion of the base, a second-stage high-pressure bin is arranged above the second-stage high-pressure bin base, a charging turbine set is arranged in the second-stage high-pressure bin, and a charging turbine driving motor is arranged in the center of one side of the outer portion of the second-stage high-pressure bin. The center of the other side of the second-stage high-pressure bin is provided with a first-stage pressurizing bin, an impeller is arranged in the first-stage pressurizing bin, a three-phase motor is arranged in the center of the right side of the exterior of the first-stage pressurizing bin, an air inlet mechanism is arranged above the three-phase motor, and a filter plug is arranged at the head of one end of the air inlet mechanism. The other end of the air inlet mechanism is fixedly connected with an air inlet port connecting end of the outer wall of the first-stage pressurizing bin, and the air inlet port connecting end is communicated with the first-stage pressurizing bin. According to the oxygen pressure high-pressure fan body, the two stages of pressurizing bins are adopted for low pressurizing and high pressurizing, step-by-step connection and progressive increase pressurizing of oxygen are achieved, the pressurizing effect is good, the pressurizing speed is high, and the pressure loss in the compression process is small.

Description

technical field [0001] The invention relates to the technical field of high-pressure blowers, in particular to an oxygen pressure high-pressure blower. Background technique [0002] A high-pressure fan refers to a fan with a wind pressure of 30kPa~200KPa or a compression ratio e=1.3~3 under the design conditions. In the current industry, gas ring vacuum pumps are generally classified as high-pressure fans. High-pressure fans, also called high-pressure blowers, are different from general centrifugal blowers. [0003] When the impeller rotates, due to the action of centrifugal force, the vane pushes the gas to move forward and outward, thus forming a series of spiral movements. The air between the impeller blades rotates spirally and squeezes the gas outside the pump body into the side channel. When it enters the side channel, the gas is compressed, and then returns to the impeller blades to accelerate the rotation again. When the air passes through the impeller and the sid...

AI Technical Summary

Problems solved by technology

[0004] The current oxygen pressure high-pressure fans all use turbines for compression, or use multi-stage turbines for stage-by-stage compression. However, there are compression gaps between such stage-by-stage compression, and there will be a large loss in compression transmission.
